Abstract: 753,840. Dispensing measured quantities of liquid. PERSIL-FABRIKKEN AKTIESELSKAB. Dec. 29, 1954 [Jan. 6, 1954], No. 37572/54. Class 106(5) A device for dispensing definite quantities of liquid from a container 13, Fig. 4, comprises a cup 1, Fig. 1, provided with a tube 2 having one or more openings 4 extending to a height corresponding to the level of the liquid desired in the cup. The device is operated by inverting the container 13 so that liquid ows into the cup 1 until it reaches the level of the top of the opening 4 whereafter the container is held in an inclined position to discharge the measured quantity from the cup 1. Drips from the cup 1 are collected in a bowl 5 secured to the tube 2 by stay ribs 6 which also serve as abutments to limit the penetration of the tube 2 into a resilient insert mounted in the mouth of the container and provided with a conical bore. The insert is connected by a band 10 to a stopper 9 which is provided wtih an additional band 12 to facilitate its removal. The device is manufactured from transparent material and may be used for dispensing washing preparations.

Abstract: 921,613. Variable - speed friction gear. SELECTRA Ltd., and E. W. KREBS. Nov. 7, 1960 [Nov. 5, 1959], No. 37631/59. Class 80 (2). Continuously variable friction gearing comprises driving and driven members 15, 16 frictionally engaging double conical idlers 20 with the semi-angle of each cone being 45 degrees and the axis of each idler being at 45 degrees to the gearing axis 19. Each idler is rotatably and slidably mounted on a spindle 23, the spindles being fast with a common ring 25 slidable along an extension 26 of the driving shaft 10, and one of the spindles carries a rack 28 engaging a pinion by means of which the idlers can be simultaneously adjusted to vary the gear ratio. The driving disc 15 is fast on the driving shaft, the driven disc 16 is journalled on the driven shaft 11 and is urged towards the idlers by spring washers 32 reacting against a bearing 13 in a fixed housing 14. The engaging pressure of the members 15, 16 with the idlers is made torque responsive by balls 33 engaging dimples in the member 16 and a ring 37 which is splined to the driven shaft. In a modification, Fig. 2, each idler has one conical surface 45 formed by the apical portion of a cone and the other surface 47 formed by a truncated cone, this arrangement providing greater reduction ratios. The inner ends of the idler spindles 23 are tied by a freely mounted disc 46, and the spring washers 32 are dispensed with.

Title: Improvements in and relating to the roasting of arseniferous minerals, such as pyrites
IPC: C22B1/10
Filed: 1957-12-11
Abstract: The arsenic content of iron pyrites is reduced by roasting the pyrites at 800 DEG C. or above in a bed fluidised by an oxygen-containing gas, which entrains the burnt material and removes it from the bed.  The sulphur dioxide content of the roasting gas formed is maintained at at least 12%.  Immediately the reaction products leave the furnace any reaction between the burnt material and the vaporized arseniferrous compounds, chiefly As2O3, is inhibited, either by physically separating the burnt material from the gases, or by rapidly cooling to below 300 DEG C., for example with water.

The dry ingredients fall through a spray of sodium silicate solution and water repellent supplied through pipe 16. The drum is heated by electric heater 9 and has vanes 7 to propel and tumble the mixture. A lining of PTFE and a brush 8 prevent sticking. The water repellent may alternatively be sprayed from a pipe 23 and glass fibres are blown in through opening 27 at the discharge end of the drum. Air is extracted through duct 32 and the tumbled material falls over an adjustable wier 31 on to a conveyer 34 from which it is intermittently discharged into moulds 35. The moulds are conveyed to a lie under a fixed platen 39 (Fig. 2, not shown) against which they are upwardly pressed by a pneumatic or hydraulic ram (40). Alternatively the tumbled material falls on to a conveyer having retaining sidewalls and is compressed by passing under pressure rollers or through a tunnel having converging side and top walls. The compressed material is dried by dielectric heating or air currents and the faces may be sealed by contact with a heated surface. Sodium silicate and polyvinyl acetate emulsion may be sprayed on to the faces for bonding a glass fibre tissue thereto by heating.
